## Description
|
24 |
+
|
25 |
+
This work proposes a *consistency distillation* framework to train
|
26 |
+
text-to-audio (TTA) generation models that only require a single neural network query,
|
27 |
+
reducing the computation of the core step of diffusion-based TTA models by a factor of 400.
|
28 |
+
By incorporating *classifier-free guidance* into the distillation framework,
|
29 |
+
our models retain diffusion models' impressive generation quality and diversity.
|
30 |
+
Furthermore, the non-recurrent differentiable structure of the consistency model
|
31 |
+
allows for end-to-end fine-tuning with novel loss functions such as the CLAP score, further boosting performance.
|
32 |
+
|
33 |
+
|
34 |
+
## Model Details
|
35 |
+
|
36 |
+
We share three model checkpoints:
|
37 |
+
- ConsistencyTTA directly distilled from a diffusion model;
|
38 |
+
- The above ConsistencyTTA model fine-tuned by optimizing the CLAP score;
|
39 |
+
- The diffusion teacher model from which ConsistencyTTA is distilled.
|
40 |
+
|
41 |
+
These model checkpoints can be found on our [Huggingface page](https://huggingface.co/Bai-YT/ConsistencyTTA).
